The present invention discloses a duty correction circuit for and method of enabling a clock signal and a clock bar signal phase transited from the clock signal by a phase difference of 180.degree. to obtain a duty of 50%. The duty correction circuit includes: a duty check block for determining the duty of a clock signal, and generating a control signal indicating a determination result; and a duty correction block for receiving the clock signal or a clock bar signal, having a phase difference o...

In an over the highway vehicle, a frame including a pair of elongate frame rails and a plurality of cross members is disclosed. One of the rails includes an integrally formed bracket projecting laterally. The bracket is adjacent a rail aperture formed by cutting the one rail to define the bracket and after such cutting bending the bracket out of a plane of the one rail.

A duty control circuit for controlling a duty factor in various industrial applications is proposed. It comprises a n-pulse counter, a m-pulse counter, another n-pulse counter, and a magnitude comparator. The magnitude comparator compares the count of the first counter with the count of the third counter and the duty control circuit gives a signal corresponding to ON when the former is larger than or equal to the latter and a signal corresponding to OFF when the former is smaller than the latter...

The modular shelf system disclosed allows for shelf construction of varying heights and/or configurations. The modular shelf system includes a first set of shelf members spaced vertically from each other and a second set of shelf members spaced vertically from each other. A plurality of interlocking leg members is coupled to the shelf members for supporting and spacing the shelf members vertically from each other. A shelf connecting clip is provided for connecting at least one shelf member of th...

A wheel includes a well base rim, also known as a drop center rim, the well of which is offset from the median plane of the rim so as to be farther from one edge of the rim than from the other. The junction between the rim and the wheel disk is in the vicinity of the edge of the rim that is the farther from the well.

A hinge adapted to connect a pair of massive elements intended to be pivotally secured, one of which is operatively stationary, is disclosed. The hinge includes a pair of flat outer plates and a flanged middle plate sandwiched therebetween. The three plates are pivotally fastened to each other by a pin or shaft extending through interlaced curled sections formed along juxtaposed edges of the respective plates. One of the outer plates is mounted on the operatively stationary element while the oth...

Improved light duty cleaning compositions comprising 15-50% surfactant on product can be formulated such that they comprise, on surfactant: a) 50-70% wt of a mixture of primary alkyl sulphate and alkyl ether sulphate, wherein the average ethoxylation value of the mixture is 0.5-2.5, b) 2-8% wt of a betaine, an amine oxide or a mixture of betaine and amine oxide, and, c) 25-45% wt of an alkylpolyglucoside surfactant. It is believed that compositions which have an excess in surfactant of a mixture...

A heavy duty vehicle rack for the attachment to the drip rails or gutters of a vehicle is useful for carrying heavy articles, such as pipes, ladders, etc. The vehicle rack has at least one crossmember which extends across the vehicle roof and has an end member on each end of the crossmember to engage the drip rail or gutter and hold the crossmember above the vehicle roof. A clamp with horizontal fastening tightly secures each of the end members to the drip rail. The end members and clamps have i...

A heavy duty floodlight having an outer housing or cowling and a separate inner housing or reflector with a lens cover adapted to tightly seal the inner housing. The cowling is provided with slots in a rear inwardly extending flange, and air scoops at the front edge extending radially beyond the frame of the lens cover to permit air to circulate through the space formed between the reflector and the cowling and the surrounding air. This circulation helps to cool the floodlight and the lamp mount...

A multipole heavy duty manually or remote control operated switch is constructed of individual pole units stacked side-by-side. Each pole unit includes first and second molded insulating members joined side to side to form a housing having a chamber, and both stationay contacts and an arc chute are within said chamber. A so-called four-bar linkage connects the switch arms to a bail connected to a common operating mechanism. When the switch is open, the movable contact ends of the switch arms ext...
